Stocks rise on hopes of resolution to US-Iran

Global stocks have edged up, oil prices have slid and the dollar has lost some safe-haven appeal as investors bet on a resolution to the Middle East war even as the US blocks Iran's ports after the collapse of peace talks.

Negotiating teams from the US and Iran could return to Islamabad this week, four sources said, days after the highest-level talks between the two countries since the 1979 Islamic Revolution ended in the Pakistani capital without a breakthrough.

US President Donald Trump said Iran wants to make a deal, but added he would not agree to any outcome that allows Tehran to have a nuclear weapon.

Hopes of a diplomatic off-ramp have helped push the S&P 500 back to pre-war levels, driven largely by gains in big tech stocks as first-quarter earnings season begins.

Europe's STOXX 600 was up 0.7 per cent on Tuesday, but remains two per cent below its pre-conflict level.

"Markets are trading hope, not resolution. The failed weekend talks did not produce a deal, but they also did not close the door on diplomacy, and that is enough for equities to keep pushing higher for now," said Charu Chanana, Saxo's chief investment strategist.

"The problem is that markets may be pricing the chance of de-escalation faster than the proof of it, so I would still expect a choppy, headline-driven tape rather than a clean risk-on trend," she said.

Nasdaq futures rose 0.4 per cent and S&P 500 futures gained 0.2 per cent ahead of a slew of earnings later, including from JPMorgan and Wells Fargo.

The dollar was heading for a seventh daily drop against a basket of major currencies, nearing pre-war levels.

Bank of America's monthly global fund manager survey for April, conducted from April 2 to April 9 and covering 193 asset managers overseeing $US563 billion, showed sentiment was the most bearish since June 2025.

The survey showed investors expect oil to be priced at $US84 by the end of the year, down from about $US98 at present.

The US military has begun a blockade of Iran's ports, angering Tehran and adding uncertainty around the key Strait of Hormuz, though shipping data showed a US-sanctioned Chinese tanker passed through the waterway on Tuesday.

Trump has said Washington would block Iranian vessels and any ships paying tolls demanded by Tehran, and that any Iranian "fast-attack" ships that went near the blockade would be eliminated.

Oil prices slid as expectations for further dialogue to end the war outweighed concerns over supply disruptions.

Brent crude futures were down 1.5 per cent at $US97.90 a barrel, while US crude futures fell 2.3 per cent to $US96.78 per barrel.

In China, data on Tuesday showed exports slowed in March as demand linked to an artificial-intelligence boom ran up against the effects of the war.

The euro rose 0.2 per cent to $US1.1782, while sterling climbed to a more than six-week high of $US1.353, putting the pound above its pre-war level.

US Treasury yields drifted lower, with the two-year yield last down 1.7 basis points at 3.7637 per cent and the benchmark 10-year yield at 4.279 per cent, down about 1.6 bps.

Rising energy prices have fuelled inflation concerns and prompted investors to prepare for the possibility that several major central banks tilt towards rate increases, a sharp reversal from pre-war expectations for cuts or an extended pause.

As a result, two-year Treasury yields are now nearly 40 basis points above late-February levels.

Elsewhere, spot gold rose nearly one per cent to $US4,784 an ounce.
